Abstract

------19/03/2021------(OCR) This invention is a invention of a 2-stage temperature-controlled rotary tray hot air dryer consisting of a structure (1) 1760 cm high, 1270 cm wide, and 1220 cm deep, made of stainless steel sheets with thermal insulation installed, with 4 wheels for moving the machine. At the back there is a section with 6 humid air ventilation fans. On the side of the machine there is a heat energy generator using combustion technology with an LPG gas burner. On the side there is a control box for controlling all the operating commands, including the on-off operation of the machine, the energy generator system, and the humid air ventilation fan system. On the top there is a section with a drive system for the rotating shaft and a hot air distribution system, which blows hot air into the drying chamber so that the temperature inside the dryer is evenly distributed. In addition, there is a drive system to drive the rotating tray frame during operation so that the hot air comes into contact with the object thoroughly and evaporates into humid air. and is thrown out of the drying chamber by a humid air exhaust fan installed at the back of the dryer. ------------ This invention is a invention of a 2-stage temperature-controlled rotary tray hot air dryer consisting of a structure (1) 1760 cm high, 1270 cm wide, 1220 cm deep, made of stainless steel sheets with thermal insulation installed, with 4 wheels for moving the machine.
